Owners Manual

NOTE: In Egress queue assignment (8 queues in S6000, 4 against in S5000 / S4810.
PFC is not applied on specific dot1p priorities.
ETS: Equal bandwidth is assigned to each port queue and each dot1p priority in a priority group.
To configure PFC and ETS parameters on an S6000 interface, you must specify the PFC mode, the ETS
bandwidth allocation for a priority group, and the 802.1p priority-to-priority group mapping in a DCB
map. No default PFC and ETS settings are applied to Ethernet interfaces.
dcb-map
Create a DCB map to configure priority flow control (PFC) and enhanced transmission selection (ETS) on
Ethernet ports that support converged Ethernet traffic. Apply the DCB map to an Ethernet interface.
Syntax
dcb-map map-name
Parameters
map-name Enter a DCB map name. The maximum number of
alphanumeric characters is 32.
Defaults None. There are no pre-configured PFC and ETS settings on S5000 Ethernet
interfaces.

Usage
Information
A DCB map is a template used to configure DCB parameters and apply them on
converged Ethernet interfaces. DCB parameters include priority-based flow control
(PFC) and enhanced traffic selection (ETS).
To display the PFC and ETS settings in DCB maps, enter the show qos dcb-map
command.
Use the dcb-map command to create a DCB map to specify PFC and ETS settings
and apply it on Ethernet ports. After you apply a DCB map to an interface, the PFC
and ETS settings in the map are applied when the Ethernet port is enabled. DCBx is
enabled on Ethernet ports by default.
The dcb-map command is supported only on physical Ethernet interfaces.
To remove a DCB map from an interface, enter the no dcb-map map-name
command in Interface configuration mode.
